actions proportioned to mass ; cyclical motions in a resisting medium, 

 furnishing harmonic indications of Sun's mass and distance ; antici- 

 pation of astronomical verifications or rectifications by means of 



varying pressures ; importance of the fu^ndamental equchtions, v = ?~' 



A ==■ ^ -in which t represents the time of cosmical, molecular, or 

 4 



atomic rotation, and g represents the acceleration of a central force. 



Dec. 18, 1863, P. ix, 283-8 (Maxwell, Edlund, Crookes, Lock- 



yer).t 

 The above was the first of a series of physicfJ papers in confirmation of 

 the following General Postulate. All physical phenomena are due to an 

 Omnipresent Poicer, acting in ways lahich may be represented by harmonic 

 or cyclical undulations in an elastic medium. 



11. On the Height of the Tides ; principles of (10) applied to the explana- 



tion of some tidal anomalies. Jan. 1, 1864, P. ix, 291-4. 



12. Daily Distribution of Heat ; coordinate thermodynamic influences of 



solar radiation, cyclical elasticit}^, and barometric pressure. March 

 4, 1864., P. ix, 345-9. 



13. Mechanical modification of electric and other elastic currents ; gravity, 



electricity and terrestrial magnetism regarded as "modes of mo- 

 tion" (Gray, Edison, Bell, Channing, Crookes); illustrations of the 



*P., Proceedings ; T., Transactions. 



t The names in parentheses are those of subsequent investigators, whose re- 

 searches have confirmed the conchisions of the papers.
